The U.S. is in serious need of the International features of X and X-2, especially the dark aeons/Penance in X and the coliseum in X-2. I just got my sixth and last Iron Duke in X-2 today and I don't even have Major Numerus to try them all out on. Then there's X: I've gotten to the point where I can beat Nemesis on my own without even having to use the aeons to take Nemesis's hits. I love these games but without the added International features they're just too easy.
